There are several java adapter classes.
MouseAdapter is one you can use to keep from having to implement all the methods of a MouseListener interface.
You creat your own extending the adapter class and then override the methods you really want to use such as the
public void mouseClicked(MouseEvent me){
//put your code in here
}
the adapter class is kind of a shell class which doesn't do anything but implement all the interface methods.
Saves time writing code.
When you want to use one of the methods you override the appropriate method in your own subclass and customize the behavior you want.
Other adapter classes:
WindowAdapter
MouseAdapter
XMLReaderAdapter
ComponentAdapter
ContainerAdapter
DragSourceAdap ter
DropTargetAdapter
FocusAdapter
KeyAdapter
